This invention relates to a device adjusting cylinder hones, with special reference to the radial adjustment of the stone carriers so that they may be accurately fitted to the work in hand, and

5 may, if desired, be readjusted during the progress of the work.

In the present adaptation of the invention, it is associated with a cylinder hone in which the stone carriers are supported bya hollow rotatable body and are adjustable radially by the longitudinal adjustment of a spindle disposed axially of a tubular shank, the latter being operatively connected in driving relation to the body.

The general object 01' the invention is to provide improved means for adjusting the relation of the adjusting spindle to the shank connected with the body, and in this connection, provision is made for determining the extent of the adjust5 ment with the utmost precision by means constructed on the principle of a micrometer.

The specific construction oi. the invention in its preferred embodiment, together with its mode of operation, will be more particularly explained in connection with the accompanying drawing, .which illustrates the same in detail.

In the drawing:

Figure 1 is a central longitudinal sectional view of the invention.

Figure 2 is a view partly in elevation and partly in section of the mechanism illustrated in the upper part of Figure 1.

Figure 3 is a transverse section taken on the line 3-3 of Figure 1.

Figure 4 is a transverse section taken on the line 4-4 of Figure 2.

Figure 5 is a prospective view of the clutch members by means of which the device is set for a predetermined adjustment,

The cylinder hone, in connection with which the invention is illustrated, comprises a hollow body 1 on which the stone carriers 2 are supported for radial adjustment. This adjustment is effected by the projection of radial pins 3, which are mounted in the body with their outer ends projecting into a recess 4 of the stone carrier, thus providing a floating support for the latter. The outward projection of the pins 3 is eii'ected by advancing a cam member 5 within the body 1, this cam member being provided with inclined surfaces engaging the inner ends of the pins 3.

The upper end of the cam member 5 is normally held in engagement with a plug 6 which has a threaded connection with the upper portion of the body 1 and may be rotated to advance the 56 cam member-5 for expanding the bone. The plug e, m the present instance, is provided with a polygonal opening adapted to receivethe correspondingly shaped end portion '7 of aspindle 8.

The upper end of the body 1 is termed with a head 9 which is cupped to receive the rounded head 10 of a tubular shank 11 through which the spindle 8 extends. The head 9 is formed at its end with radial slots '12 for receiving'pins 13 which project from the head 10 to establish a driving connection. This connection is maintained by a washer 14 which fits the upper part oi the head 10 and is held within a cap lfi'which is secured to the upper end of the head 9 and retained thereon by means of a lock nut 16. Thus it will be seen that the shank 11 has a limited universal movement with relation to the body 1 while its driving connection with thelatter is maintained. The spindle 8 normally rotates with the shank 11 during the honing operation, but for the purpose of expanding the hone, when oc casion requires, the shank 11, by means hereinafter described, may be rotated relatively tothe spindle 8 and plug 6, thereby advancing the latter and also the cam member 5. V

The shank 11 is adapted to be driven from a chuck or sleeve 17, the lower endoi which is provided with a bayonet slot 18 for receiving a pin rotatably mounted within the sleevel'l and is held against longitudinal movement in the sleeve by a pin or screw 25 extending inwardly from the sleeve into a circumferential channel 26 formed in the clutch member. The upper iace oi the clutch member 24 is formed with teeth 27 which are adapted to interlock with teeth 28 formed on the opposed face of a complementary clutch member 29. The clutch member 29 has a limited longitudinal and rotational movement within the sleeve 17 but is normally held in interlocking engagement with the member 24 by means of a spring 80 interposed between the upper face of the member 29 and the lower end oi. the driving member 21.

. A pin 31 issecured diametrically in the clutch todisengage the teeth 27 and 28, permitting a partial rotation of the member 29 while the member 24 remains stationary, the extent of such movement being limited by the length of the slot 32, which preferably extends for about one third of the circumference of the sleeve.

The sleeve 1? is surrounded by a drum 33 which receives the outer end of the pin 31, thus securing the drum to the member 29. The sleeve 17 is also provided with a hole 38 so that the pin 31 may be knocked out when it is desired to disassemblethe device.

In the normal operation of the hone, the member 21 is continuously driven, thereby driving the sleeve 17, the shank 11 and the body 1 on which the stone carriers 2 are supported. The spindle 8 is adapted to be driven by the clutch member 24 which in turn is driven by the member 29; If the pin 31 is engaged by the rear end of the slot 29, it follows that the spindle 8, the plug 6 and the cam member 5 will be drivenin unison with the body 1. If,.however, the pin 31 is not at the rear end of the slot 29 the spindle 8 will remain stationary while the sleeve 1'7. advances until the end of the slot engages the pin. This partial relative rotation causes the plug 6 to rotate withinthe body to advance the cam member 5 and expand the hone.

When it is desired to expand the hone, therefore, the drum 33 may be raised, together with the clutch member '29 and partially rotated with relation to the member 24. For the purpose of space on the scale 34, or it may be advancedfor the entire length of the slot 32. Then in order to positively insure the expansion of the hone, the drum 33 may be gripped by a brake-band, indicated at 39, while the power is applied to the member 21. This will prevent the rotation of the spindle 8 until the rear end'of the slot enparticularly adapted for production work, it is apparent that the same construction may be used in reconditioning work and may, in fact, be used in connection with any mechanism wherein it is desired to effect a relative rotational adjustment of one member with respect to another, which is co-axial therewith.

What I claim is:

1. In a cylinder hone driving and adjusting mechanism,,a sleeve constituting a drive member, a hollow shank driven thereby, a clutch member within' the sleeve guided for rotation relative thereto, a spindle keyed to said clutch member and extending through said shank, a co-operating clutch member in said sleeve normally rotatable in unison therewith and held in engagementvwith the first mentioned clutch member,

but movable for a limited distance out of engagement with saidfirst mentioned clutch member and forwardly with reference to the sleeve, whereby the latter may then advance through a partial rotation without driving said spindle.

2. In combination, a rotatable sleeve, co-operating clutch members carried by the sleeve, a spindle keyed to one of saidclutch members, a connection between one of said clutch members and said sleeve including a circumferential groove with a pin engaging the same and permitting relativerotation of the sleeve and clutch member
